y s 1 'I OF NEW YORK Y Y WATER TURBINE Application led Decemluer Thisinvention relates generally to power devices, and has more particularreference to a novel water wheel adapted for engaging in a movingstream.

The invention has for an object the provision of a device of the classmentioned which is of simple durable construction, desirable in use andefficient in action, and which can be manufactured and sold at areasonable ldcost.

The invention proposes the use of a cylindrical body having closed endsand rotatively supported transversely in a stream of water. Main paddlewings are pivotally mounted `15`along the sides of the cylindrical bodyand have projecting hooks for forming stops for small wings pivotallyconnected on the hinge points of the main wings for forming comv poundwings. A weight is supported on a Hexible member attached on the smallwings and arranged for opening` the small wings at desired times so asto move the main wings into operative positions.

It is pointed out that a machine constructed `according to thisinvention will receive power from the moving stream and this power maybe transmitted to an electric generator for supplying electric current.

For further comprehension of the inven- Ttion, and of the object andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing, forming a material part of this disclosureFig. 1 is a vertical transverse sectional view of a stream of water andthe device applied therein.

Fig. 2 is a vertical sectional view, taken on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary perspective view y `of the cylindrical body andthe compound `wing arrangement thereon.

Fig. 4 is a vertical sectional view, taken on the line 4 4 of Fig. 3.

Fig. 5 is a vertical sectional view, taken non the line 5--5 of Fig. 3.59 The reference numeral 10 indicates gen- 1, 1928.l Serial No. 323,099.

erally a moving streamand 11 indicates its bottom. A concrete foundation12 is built on the bottom 11 and extends upwards out of the stream ofwater. This foundation is constructed in the form of a housing and atits top endis provided with a cover 13. A sec-` ond foundation housing14 is also built upon the bottom 11, but is of small height so as not toextend out of the water. This housing is provided with a cover 15.Standards 16 are mounted on the base of the housing 12, and a standard17 is mounted within the housing 14. A shaft 18 is rotatively supportedwithin these standards. l

A cylindrical body 19 having closed ends 20 is .fixed upon this shaftbetween the said standards. At one end, the shaft is provided with abevel gear 21 meshing with another bevel gear 22 fixed on a shaft 23rotatively mounted in the housing 12 and vertically arranged. A bevelgear 24 is fixed onto the `top end of the shaft 23` and meshes with abevel gear 25 on the shaft of a generator 26. The generator is shownwith power leads 27.

Main paddle wings 28 are provided at their lower ends with lixed shafts29 rotatively mounted on the sides of the cylindrical body as, bystandards 30. Small wing members 31 are pivotally mounted on their loweredges, as at 32 on the shafts 29` and are positioned on the rear sidesof the wings 28. The front sidesof the wings 28 may be defined as thesides against which the stream of water acts for rotating thecylindrical body. A pair of hooks 33 project rearwards from the mainwings 28 and serve as a limiting means for the amount which the wings 31may open. Flexible members 34 are attached onto the small wings 31 andweights 35 are arranged on these flexible members.

The main paddle wings 28 are formed with projecting stop members 36 forlimiting their motion to a radial position. These wings may also move toa substantially tangential p position disposed towards their front.These stop lugs 36 project through apertures 37 formed in the smallwings 31 and abut against the cylindrical body 19.

In Fig..4 a main paddle wing 28 is illustrated in full lines in itsradial position. Dotetv CTI

dash lines 38 indicate the main Wing 28 assuming tangential position.

In operation of the device, the cylindrical body 19 turns by reason ofthe moving stream 10 acting against the compound Wings. The motion istransmitted by the system of bevel gears to the electric generator 26which generates electric oWer for general use. The compound ad le Wingsare so arranged as to assume radial positions whilel at the loweryportions of the cylindrical body and as the' water acts against the mainpaddle wings for rotating the cylindrical body the compound Wings arearranged tomove to sulv stantially tangential positions as beforestated, on. the sideA of the cylindrical body away from the direction ofthe motion of the` stream. Arrows.l 4:0 in F ig. 2 indicate thedirection of the stream` Theweights 35 act to.` draw the small Wingsopen after the compound Wings pass the top position on the cylindricalbody. It is seen that the weight hangs downwards and finally drawsy thesmall' Wings o aen, then the small wings rest against the hoo elements33. They remain inl this condition during rotation of the cylindricalbody through an angle of' approximately 100 degrees and then thestreamacts against the front side of the main paddle Wings for rotatingthe cylindrical: body. It isiseenv that theV weight then closes thevsmall Wings against the Irwin wings as the cylindrical body turnsfurther. The main wings may then tilt' towards the: front for assumingt1' positions as shown in. Fig. 2;.

While I have-shown and described tliepreferred embodiment of my"invention, it is to be understood that I do not limit myself to theprecise construction herein disclosed: and the right is reserved to.Iall changes and modifications coming within the scope of the inventinaafs-defined inthe appended claims.

Having thus described my invention, what I claim as-new, anddesirezto-secure by United States Letters Patent is 1. In a device ofthe class described, a cylindrical body provided with pivotedi mainwings and4 a small wing pivotally mounted on the point of each of themain Wings and disposed to ,the rear of each main7 Wing and arranged formoving the main Wing from a substantially tangential positionrearwardsupon rotation of the cylindricalbody, and a stoprmember projecting fromthe rear face of' each of the main wings andv passing thru an aperturein the small Wing and its free end beingabuttable against the cylinderfor'limitin rearward? motion` of the main Wing to a ra ial position.

2. In a device of the class described7 a cylindricalf body provided withpivoted main Win and' a smallV wing pivotally mounted on t e hinge pointof each of. the main Wings amd` disposedy to. the rear ofeachmain' Wingand arr'. for moving the' main Wingf signature'.
